徕卡10-25mm F1.7因其卓越的锐度、美丽的散景和坚固的做工而广受赞誉，是Micro Four Thirds相机上摄影和摄像的顶级选择。用户强调其恒定f1.7光圈、手动对焦离合器和无级光圈环是突出特点。然而，它被指出对于该系统来说又大又重，价格高昂且没有光学防抖，一些用户报告在视频模式下自动对焦会犹豫。尽管有这些缺点，大多数人仍认为它是一款提供不妥协画质的出色镜头。
优点
- 所有焦距下均具有出色的锐度
- 美丽的散景
- 恒定f1.7光圈
- 坚固的做工
- 平滑的手动对焦离合器
缺点
- 对于MFT系统来说又大又重
- 价格高昂
- 没有光学防抖
- 视频模式下自动对焦犹豫
- 在小机身上头重脚轻
